What better way to celebrate it than to remember one of the best if most unconventional father/son relationships in comics?
Booster Gold and Rip Hunter!
Remember how Rip was trying to help Booster become the greatest most selfless hero of all time? How about how annoying that could be?
Then the utter amazement when Booster was able to do something by himself?
I miss these two more than any other DC relationship.
